..This study shows that the prevalence of enteropathogenic Yersinia is high and both enteropathogenic Y. enterocolitica and Y. pseudotuberculosis are common findings in tonsils of wild boars in Switzerland...

Prevalence of pathogenic Yersinia enterocolitica in pigs slaughtered at a Swiss abattoir

..The indistinguishable genotypes among human and porcine strains together with different genotypes in Finland and Germany indicate that pigs are an important source of sporadic yersiniosis in both countries...

Different Yersinia enterocolitica 4:O3 genotypes found in pig tonsils in Southern Germany and Finland

M Fredriksson-AhomaaInstitute of Hygiene and Technology of Food of Animal Origin, University of Munich, GermanySyst Appl Microbiol 26:132-7. 2003

..These results indicate that Y. enterocolitica 4:O3 genotypes have a differential geographical distribution and thus can be used in epidemiological studies...

Different genotypes of Yersinia enterocolitica 4/O:3 strains widely distributed in butcher shops in the Munich area

..In conclusion, raw pork products from butcher shops are frequently contaminated with different genotypes of pathogenic Y. enterocolitica 4/O:3, thus serving as an important transmission vehicle from butcher shops to humans...

High prevalence of Yersinia enterocolitica 4:O3 on pig offal in southern Germany: a slaughtering technique problem

M Fredriksson-AhomaaInstitute of Hygiene and Technology of Food of Animal Origin, University of Munich, GermanySyst Appl Microbiol 24:457-63. 2001

..enterocolitica 4:O3 from tonsils to the carcass, and subsequently, to meat...

..This study shows that wild boars are frequent carriers of foodborne pathogens. High wild boar densities and increasing popularity of outdoor ranging of pigs may intensify the risk of transmission of these pathogens to fattening pigs...

..enterocolitica in natural samples is clearly higher with PCR than with culture methods. The methods available for detection of pathogenic Y. enterocolitica in natural samples are reviewed in this article...

..enterocolitica 4/O:3 strains persisting among slaughter swine were demonstrated to be very stable genetically. This study shows that fattening pigs are an important reservoir of different genotypes of Y. enterocolitica 4/O:3 strains...

Prevalence and characterisation of yadA-positive Yersinia enterocolitica in pig tonsils in 1995 and 1999

..The existence of similar L. monocytogenes strains in various food products of several producers should be considered if food strain fingerprint results are used to help trace the vehicles for infections...
